Answer 1

Sita can cut 8 onion=10 min
So she cut 1 onion = 75 sec

As it's jyoti can cut 6 onion=5 min
1 onion=50 sec
Now both cut 1 onion = 30 sec
Then 24onions =( 30×24)/60=12 min

Answer 2

Answer:

Time taken to cut 24 onions together is 12 minutes.      

Step-by-step explanation:

Given : Sita can cut 8 onions in 10 minutes and Jyoti can cut 6 onions in 5 minutes.

To find : How much time will they take to cut 24 onions together?

Solution :

Sita can cut 8 onions in 10 minutes.

In 1 minute Sita cut = $\frac{8}{10}$ onions

Jyoti can cut 6 onions in 5 minutes.

In 1 min Jyoti cut = $\frac{6}{5}$ onions

Together in 1 min they cut $\frac{8}{10}+\frac{6}{5}$

Together in 1 min they cut $\frac{8+12}{10}$

Together in 1 min they cut $\frac{20}{10}$

Together in 1 min they cut 2 onions.

So, 2 onions cut in 1 min.

Then 24 onions cut in $\frac{24}{2}=12$ minutes.

Therefore, Time taken to cut 24 onions together is 12 minutes.
